It is unknown how to identify a small pulmonary vein thrombosis that is not contrasted because of loss of blood flow. Ischaemic stroke is an important clinical problem, and its prevention is a clinical target for the treatment of atrial fibrillation (AF). Because cardiac thrombus, a thrombus in the left atrial appendage and the left atrium, is well known, pulmonary vein thrombosis is thought to be a rare complication following lung surgery and catheter ablation. However, we have reported some cases of pulmonary vein thrombus without surgery, indicating that pulmonary vein thrombosis is not rare. In this case, we provide the details of an unenhanced pulmonary vein thrombus on 64-slice multidetector CT, which was largely illustrated in our previous case report. Because we understand the processes of the formation of pulmonary vein thrombus, we recognise an important implication of pulmonary vein thrombus; it alters hypoxic circumstances and under-nourished state.
由于血流丧失而未显影的小肺静脉血栓如何识别尚不清楚。缺血性中风是一个重要的临床问题，其预防是心房颤动（AF）治疗的临床目标。由于心脏血栓，即左心耳和左心房内的血栓是众所周知的，肺静脉血栓被认为是肺手术和导管消融术后的罕见并发症。然而，我们报告了一些未经手术的肺静脉血栓病例，表明肺静脉血栓并不罕见。在本病例中，我们提供了64层螺旋CT上未增强的肺静脉血栓的详细情况，这在我们之前的病例报告中有大量说明。因为我们了解肺静脉血栓形成的过程，所以我们认识到肺静脉血栓的一个重要影响；它会改变缺氧环境和营养不足状态。
